VIRGINIA GRAEME BAKER
POOL AND SPA SAFETY ACT
The Virginia Graeme Baker Pool and Spa Safety Act (VGB) was signed
into federal law on December 19, 2007 and requires all public swimming
pools and spas be compliant by December 19, 2008.
Public swimming pools and spas must replace their suction outlet covers
with drain covers that meet the ASME/ANSI A112.19.8 performance
standard. VGB Compliant drain covers are tested and rated for flow rates
relating to body and hair entrapment. Each drain cover is listed with specific
flow ratings, based on whether the drains are placed on the floor or on the
vertical wall.
The VGB Act identifies remedies for pools and spas that have
single drains, multiple drains, and exceptions for pools or spas with
"unblockable drains" (drains more than 18" x 32" in size, with an open
area diagonal of more than 29 inches). The additional remedies include:
adding an additional drain (if you have a single drain system), installing a
Safety Vacuum Release System (SVRS), installing a suction limiting vent
system, installing an automatic pump shut-off system, installing a gravity
drainage system, or considering drain disablement or reversal of flow.
Be sure to contact your local health department to insure compliance.

Commission website at www.cpsc.gov or our Lincoln website at
